Lesson 2: Concave & convex mirrors and their applications

# Convex mirror & applications

When curved mirrors have a reflecting surface on the outside, they are called convex mirrors. (vex stands for bulging out). Let's learn what they do and their applications in our day to day life.  Created by Mahesh Shenoy.

• If 'vex' means bulged out , and 'cave' is taken from natural caves. What does 'con' mean?
• The word convex comes from the Latin convexus which means vaulted or arched out. Whereas concave comes from concavus which means hollowed out.
• Aren't there any other applications of the convex mirror? these both are the very common ones.
• Convex mirrors are also used in various other places like as a street light reflectors as it can spread light over bigger areas. They are also used to make telescope and ceiling dome mirrors. our sunglasses too are convex mirrors
• if the rays do not meet at all.... why do we consider them meeting
• this is the same reason why hollow-face illusion works, our brain doesn't simply show what is present;it processes the visual information according to previous learning from experiences.like,in this very case,we see an object with the same bright surfaces , dark surfaces and shadows as the real one, our brain assumes that the image is a real one.a object can only be visible when rays diverging from it reach the eye,so our brain assumes that the rays are diverging from the image rather than they being reflected.
• Are laws of reflection valid for diffused
reflection?
